Patent GB-1143815-A (GB)
IPC: H01L21/60
Abstract: 1,143,815. Soldering. INTERNATIONAL BUSINESS MACHINES CORP. 3 June, 1966 [18 June, 1965], No. 24733/66. Heading B3R. [Also in Division C3] A method of attaching an electrical component to a printed circuit on a substrate member comprises forming discrete areas on the circuit which are solder wettable surrounded by non- wettable areas, mounting the component with solder interposed between its terminals and the areas and heating to melt the solder and thereby to attach the component, surface tension forces maintaining the component spaced from the substrate while the solder is molten. Typically the component may be a semi-conductor device having projecting solder contact or terminal points and solder may additionally be applied e.g. by dip coating to the solder wettable areas of the printed circuit. Rosin or other suitable flux is applied to the solder points on the printed circuit by brushing, spraying or dipping before the component is applied thereto. The printed circuit conductors may consist of a material which is not solder wettable and the required solder wettable areas formed by printing dots of wettable material thereon or by treating the conductor surface to render it wettable; alternatively the conductors may be of a solder wettable material and the required areas marked off by the application of a non-conductive, non-wettable material such as a glass frit or polymeric material; alternatively again as shown in Fig. 5, the solder wettable conductive material 24 may be applied directly to the substrate 20, and non-wettable conductors 22 printed so as partly to overlap the material 24, solder 26 being applied to the exposed parts of the material 24 which subsequently becomes united to the solder 6 projecting from the semiconductor device 4. The preferred solder composition is between 5 and 40% tin and 95 to 60% lead but other low melting point alloys which may be combinations of indium, gallium, silver, gold and antimony may be used. The conductors which are non-wettable by solder consist primarily of a noble metal but contain also a high melting point metal oxide (see Division C3) and can be rendered solder wettable by polishing or abrading the surface.

Abstract: 1,225,373. Brick-laying apparatus. P. M. THOMAS. 14 May, 1968, No. 22777/68. Heading EIS. Horizontal brick, &c joints are formed using e.g. a clamp (Fig. 3) or a supporting tray (Fig. 11) to hold the brick mechanically, virbrating the mortar bed, using, e.g. vibrators 10 on the clamp or vibrators 43 on the tray, and locating the bricks at the correct level using the supporting surface for the first brick course as a datum. The tray is used to support bricks 37 with vertical mortar layers 39 therebetween, and a mortar layer 38 thereon, the tray being lowered by a frame 41 with prongs 46 thereon which press the bricks down. When the bricks 37 are at the desired height, slides (45), Fig. 12 (not shown) are withdrawn, to which the horizontal fingers 40 forming the tray are attached. Vertical mortar layers can alternatively be formed independently of the horizontal layers using a hopper (16), Fig. 4 (not shown) with vibrators attached, in combination with stirring rods (23) attached to a further vibrator (18), or in combination therewith using a similar hopper (26), Fig. 8 (not shown) with a rear extension (31) to form the horizontal layer. A hopper for laying horizontal mortar layers only is illustrated in Figs. 1 and 2 (not shown).

Abstract: 1,226,283. Magnetic heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 May, 1969 [21 May, 1968], No. 25127/69. Heading G5R. A magnetic recording apparatus, in which a record is partly wound on a drum provided with at least one magnetic head which successively scans from one edge of the record to the other, has the or each head bevelled 15 at one trackdefining edge of the gap 14. The upper drum half 2 is rotated in the opposite direction to a tape 9 transported round the drum and consequently the tension in the tape leaving is greater than that approaching the drum. By reducing the contact area in the lower half of the head, the pressure exerted on the head in crossing from one tape edge to the other is maintained constant and there is less loss of signal (Fig. 3, shown). The head, Fig. 4, consists of ferrite core parts 16, 17 with a glass gap-forming material 14. The apparatus may be of the 180 degrees wrap type and provided with two heads.

Abstract: 1,227,754. Fuelling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 July, 1968 [21 July, 1967], No. 33790/67. Heading G6C. A bucket 1 for transferring an irradiated fuel sub-assembly (not shown) form an immersed storage position in a sodium-cooled reactor, has a seat 2 for supporting the lower end of the sub-assembly and an open top member 8 having a lip 9 for engagement by a grab. The fuel pins of the sub-assembly extend from the seat 2 up to just below a ring 4, the remainder of the sub-assembly extending into the upper part 5 of the bucket 1. When the sodium-filled bucket is lifted from the storage position the heat emitted by the sub-assembly therein causes the sodium to expand and this would cause sodium to be spilt from the top member 8 during the transfer of the bucket to an external fuel facility. To prevent this spillage the upper part 5 comprises inner and outer cylindrical walls 14, 13 enclosing an annular space 15. Equi-spaced in the space 15 are four inverted U-tubes 18 which function as syphons. Each tube 18 has a longer arm 19 and a shorter arm 20, the end of the latter communicating with the interior of the part 5 through an aperture 21 in the wall 14. A series of drain holes 16 are provided in the wall 13 just below the level of the ends of the arms 19. In use, the bucket 1 is raised from the storage position until the holes 16 are just above the sodium level in the reactor whereby the sodium is emptied from the bucket by the syphon tubes 18, the sodium leaving the annular space 15 through the holes 16 until the sodium level in the bucket has fallen to the level of the apertures 21. Thus on subsequent transfer of the bucket from the reactor the remaining sodium may expand into the upper part 5.

An apparatus for manufacturing a composite mouthpiece rod, includes a device having n inlet passages for filter plugs or components and a single outlet passage so that n types of plugs or components can be fed into the inlets, one type to each inlet, to produce a single line of plugs or components from the outlet. As shown, three types of plugs are fed into three bores 2, 3, 4 in a block 1 and which bores merge into a single outlet passage in the form of a bore 5. Three nozzles 6, 7, 8 are positioned in a single plane through the block 1 to inject compressed air into, and in a direction normal to the axes of, the bores 2, 3, 4, and the plugs in each stream are staggered with respect to one another. Continuous blasts of compressed air from the nozzles 6, 7, 8 thus project a plug of each type in turn into the bore 5 to form therein a stream of plugs of the three types in sequence. The plugs are fed from three mutually geared hoppers (not shown) on to fluted drums and then by pushers to the bores 2, 3, 4 by arrangement similar to that shown in Fig. 2 of Specification 971,491 for feeding plugs to the discs (25). A worm (not shown), similar to that shown at (15) in Specification 971,491, is sited downstream of the block 1 and serves a similar purpose to that in said prior Specification.

Abstract: 1,250,439. Respirators. PYE Ltd. 7 April, 1970, No. 16339/70. Addition to 1,248,303. Heading AST.  In a medical respirator according to the Parent Application Specification 1,248,303 the movable member, comprising two diaphragms 109, 110 linked by a distance piece 111 which carries a spring 113, controls the operation of the switching means, a spool valve 133. The linked diaphragms have connected to them a rod 119 through which is slotted a rod 126 which connects at one end with the spool of valve 133, carries at the other end a pole piece 134 and is pivoted on pin 125 to a plate 124, thus forming a mechanical linkage between the diaphragms 109, 110 and the spool of valve 133. In its extreme positions the pole piece 134 abuts magnets M1, M2 respectively. During the inspiratory period of the respirator gas is fed into volume V2, from a gas source 135 via a pressure control means 137, thus expelling gas from volume VI along a line 142 to a port A of spool valve 133 and out from port B to the patient via adjustable restrictive means 144. As V1 reduces in capacity the rod 119 is forced to the right, spring 128 overcomes the magnetic attraction between the pole piece 134 and the magnet Ml and the pole piece 134 moves to the magnet M2 moving the spool of the valve 133 so that ports A and C thereof are in communication. The restrictive means 144 controls the duration of the inspiratory period. The movement of the spool starts the expiratory period. The force exerted by the spring 113 pulls the linked diaphragms to the left thus forcing the gas out of V2 and into V1 via adjustable restricting means 140 and the valve 133, and pole piece 134 moves back to magnet Ml. The restricting means 140 controls the duration of the expiratory period. In a second embodiment, Fig. 2 not shown, the movable member is a spool (202) which controls the spool valve (133) by controlling gas flow to the valve.

Abstract: 1289710 Television GENERAL ELECTRIC CO 23 Dec 1969 [8 Jan 1969] 62665/69 Heading H4F A full (demodulated) NTSC signal 22 with half line offset is supplied directly and after 90 degrees subcarrier delay in a line 11, to respective four quadrant double balanced true product multipliers, e.g. at an input B, via capacitors which reject the lower frequency luminescence components, a further input A of each multiplier being supplied with a reference subcarrier from an oscillator 17. Each multiplier comprises a differential amplifier 45, 46, the balanced outputs of which are determined by signal B and form the control currents for a further pair of differential amplifiers 41, 43 and 42, 44 fed with signal A. The multiplier outputs AB contain some luminescence information as well as the chrominance signal, but the luminance which is not removed by vestigial low pass filters 17, 18 will cancel visually in successive lines and frames due to the half line offset. As shown, a 33-degree tap 23 on the line 11 provides the colour bust and hence the reference subcarrier is phased so as to give I and Q demodulation. In Fig. 4 (not shown) the bust is not delayed to give R-Y and B-Y demodulation. Since the multipliers are double balanced, connections may be made so that the positive product AB is obtained. The signal 22 is further delayed in line 11 (typically 0.4-0.7 nanoseconds) to achieve time coincidence of the three output signals, e.g. I, Q, and, effectively, Y, for matrixing purposes.
